Application July 7, 1949, Serial No. 103,461

This invention relates to the-storage of material in warehouses and hasspecial reference to means for conveying material tobe stored to thepoint of storage, there placing it and then, when desired, withdrawingit. It is recognized that it has been customary to place material forstorage on a pallet which is a small platform upon which can be stackeda charge of merchandise or product. It is recognized that it is quitecustomary to shift such pallets from one place to the other bymechanical means. These pallets are picked up and transported by lifttrucks, or the like, but therefore there is a distinct limitation to theload capacity of this work.

It is one of the principal objects of this invention to providemechanism whereby a full master load of any product without being placedon a pallet may be suitably stored in a warehouse by mechanical meansand withdrawn therefrom as desired.

Another important object of the invention is to provide a mechanismwhereby heavy loads of material may be moved from one place or anotherbeside a warehouse, raised to the proper position for dispositionandthere placed in the warehouse without manual intervention, such load ofmaterial being as readily withdrawn from the warehouse position.

Anotherimportant object of the invention is to arrang the depositingstructure and the warehouseso that no necessityis afforded of placingone load on top of the other, a common practice with loads carried onpallets.

Another important object of the-invention is to provide a novelmeohanismfor handling materials stored in a warehouse whereby suchmaterials are immediately available for withdrawal from the warehousewithout making it necessary tomove any other materials.

A further important object of the invention is to provide a mechanismwhereby any of the materials in the warehouse may be instantly removedwithout interference with other materials therein.

A still further object of the invention is to provide a warehousingmechanism by which a load of materials may be stored in the warehouseand never moved out of the way of other materials stored therein untilit is desired to withdraw the particular materials from the warehouse.

Another important object of the invention is to provide a mechanismwhereby material may be withdrawn from a warehouse at any time withoutinterfering with material which has been deposited later;

10 Claims. (01. 214-4612) Another important feature of the invention isto provide a mechanism having a novel construction of retractablestorage beds eliminating the necessity for using a pallet wherebymaterial may be readily moved into and out of a warehouse.

Again it is an object of the invention to provide a mechanism forstorage of material in and withdrawal of the same from a warehousethereby requiring life truck operation parallel with the longitudinalaxis of the, aisle only elim inating the necessarily wide aislesrequired when life trucks are used in order to carry material from onepoint to the other in the Warehouse, and thereby not requiring aisles oisinficient width to allow a turning radius for operation perpendicularto the longitudinal axis of the aisles.

With the above and other objects in view the invention consists ingeneral of certain novel details of construction and combinations ofparts, hereinafter fully described, illustrated, in the accompanyingdrawings and particularly claimed, like characters of referenceindicating like parts in the several views; and

Figure 1 is a diagrammatic plan view of arrangement of warehouses andthe apparatus for placing and removing loads;

Figure 2 is an end elevation of the arrangement shown in Figure l, theview being taken looking along the aisle between the warehouses;

Figiu'e 3 is a partial side view of one of the retractable storag bedsused in this invention, showing said retractable storage bed within oneof the compartments of warehouse;

Figure l shows a continuation of the righthand side of Figure 3;

Figure 5 is a plan view partly in sect-ion, showing the arrangement ofthe transfer bridge;

Figure 6 is an elevational view partly in section of th crane transferbridge, showing the retractable storage bed drawn out of warehouse ontosaid bridge, and the suspension means for the bridge;

Figure '2 is a detailed view looking from the upper right-hand part ofFigure 6;
